Question

Earth is approximately 1.5x10^8 km from the sun. how many minutes does it take to travel from the sun to the earth? the speed of light is 3x10^8 m/sec

Answer 1

8.33 minutes will it take to travel from the sun to the earth.

Explanation:

Distance of the Earth from the Sun = d =
`1.5* 10^8 km`

1 km = 1000 m

`1.5* 10^8 km=1.5* 10^8 * 1000 m=1.5* 10^(11) m`

Speed of the light, s =
`3* 10^8 m/s`

Time taken by the light to travel from the sun to the earth = T

`Speed=(Distance)/(Time)`

`s=(d)/(T)`

`T=(d)/(s)=(1.5* 10^(11) m)/(3* 10^8 m/s)=500 s`

1 min = 60 seconds

T = 500 s =
`(500)/(60) min=8.33 minutes`

8.33 minutes will it take to travel from the sun to the earth.

Answer 2

Distance of earth from the sun = 1.5 x 10⁸ km
speed of light = 3 x 10⁸ m/s
time in minutes = ?
by using the formula,
Distance = velocity x time, we get
time = distance/velocity
time = t = (1.5 x 10⁸) / (3 x 10⁸) = 0.5 seconds
convert 0.5 seconds to minutes = 0.00833333
it takes 0.00833333 minutes to travel from the sun to the earth
